I'm with you, ChuckW, re disappointment with the Pilot's antenna performance. I've posted elsewhere about my problems with signal strength. I receive a decent signal for only a handful of AM/FM stations, and even the strongest of those weakens at times. The "search" feature on the radio is useless; it lands on only a couple of stations; no other signals are strong enough. I live about 25 miles from both Washington and Baltimore, so I'm not exactly out in the boondocks.
Somehow I doubt the service dept. will find anything wrong when I take the Pilot in for the first oil change....and will probably just say "that's what you have to put up with when you don't have an external antenna." But I don't see too many others complaining about this on this board. I'd welcome anybody's insight/suggestions.
